One way to find out if a caterer has experience with events similar to yours is to ask for references or to look for reviews and testimonials from previous clients. You can also ask the caterer directly about their experience and if they have handled events of a similar size, style, and cuisine. Additionally, checking the caterer's portfolio or website to see photos and descriptions of past events they have catered can also provide insight into their experience and abilities. If you are looking for a  USA top tier catering service, you may also want to consider reaching out to event planners or venues for recommendations and referrals.
